Photometric scaling relations of all investigated galaxies. Except for the total magnitude (curve-of-growth), all quantities arise from single Sérsic fits. In the case of spiral galaxies, the fit was performed to the disk; for dE,N only the main body was fitted. Symbols as in Fig. 7. While r_e is the effective radius, μ_e represents the effective SB (at r_e). The gray line in the μ_e − M_R-plot gives the relation of Misgeld et al. (2009). The disrupted galaxy is not shown in this plot (no light profile available).
